NAME
look -- display lines beginning with a given string
SYNOPSIS
look [-df] [-t termchar] string [file]
DESCRIPTION
The look utility displays any lines in file which contain string as a prefix. As look performs a binary search, the lines in file must be sorted. If file is not specified, the file /usr/share/dict/words is used, only alphanumeric characters are compared and the case of alphabetic char- acters is ignored. Options: -d Dictionary character set and order, i.e. only alphanumeric characters are compared. -f Ignore the case of alphabetic characters. -t Specify a string termination character, i.e. only the characters in string up to and including the first occurrence of termchar are compared. The look utility exits 0 if one or more lines were found and displayed, 1 if no lines were found, and >1 if an error occurred.
FILES
/usr/share/dict/words the dictionary
COMPATIBILITY
The original manual page stated that tabs and blank characters participated in comparisons when the -d option was specified. This was incor- rect and the current man page matches the historic implementation.
